I'm little confused on how to connect these two up. I thought the basic way would be to use s-video to s-video cable (together with the optical connector) to connect dvd to amp and then s-video to scart from amp to the tv would work? But it doesn't. I get sound ok, but no display. I also can get the on screen menu for the amp. I understand the output from the amp should be monitor out? What am I doing wrong?
